AA B757 Exp. Decompression, FL310 due 1' x 2' hole in fuselage

All safe.

A/C with approx 60,000 hours had a decompression on flight 1640; MIA-BOS on Oct. 26th.
A 1 foot by 2 foot piece of the fuselage skin peeled back inflight causing explosive decompression at FL310.

Anyone have pics?

Just use the pics from Southwest flight 229

May as well use this





Once you've seen some peeled back skin, you've seen em all

"A/C with approx 60,000 hours had a decompression on flight 1640"

If so, something might have been missed on a couple of D-Checks. Anybody know what the disposition of the SWA incident was?

Aft fuselage crown skin, perhaps?
IF so, seems a Boeing trouble prone area...even from the 707 days.

Isn't that because some fuselage sections from the 707 were never changed in any of the narrowbodies?

Similar construction technique.
Initially, with some 707's, fuselage skin cracking was noticed, just above the aft door, on the fuselage crown.
External straps were fitted, for a maximum of 2500 cycles, then reskinning was accomplished.
This was a problem with the forward fuselage crown skin as well, but not quite so severe.
As I recall, heavier skins were then used on the -320B/C models.

any press reports yet quoting the usual..

"..thought we were going to die.."

"...crash landed.."

"...narrowly missing a school/hospital/orphanage.."

... i could do with a laugh this morning !

Anyone know what "disposition" means in relation to an aeroplane incident?

I assume it's a transatlantic expression - it means nothing to us in Europe and the dictionary gives no help...

Final outcome....IE: the end result.

Surely it should have sucked half the passengers out.....

As it was an AA flight I doubt any American will be brave enough to suggest they could fit through a 1ft x 2ft hole, last AA flight I was on many of them on board were lucky to get through the bloody door!!!

HI
Not a frequent poster, but curious about this one

if a rotund person of any nationality happened to get sucked or pushed, the latter being more technically correct i guess, and they plugged up the hole, what are the implications of the "fluid hammer" effect of all the air rushing towards the hole, then having no where to escape to? could it cause a catastrophic failure of the structure?

many thanks

VFR 750,

Air is compressible, so no hammer effect like hydraulics. And, there are a couple things called "pressure relief valves" to prevent (whatelse) over pressure.

Holes in fuselages are fairly rare, but they do happen, and the structures engineers have done a good job designing them , so when they do fail, the damage doesn't do what the movies think they will.

cheerio

With respect, I think I'm a fairly chilled out passenger, with a good pprune education, but I think I'd have been a bit worried to see a hole appear in the fuselage.

I know most incidents are non-events to those in the industry, but bear in mind that most SLF have little aviation knowledge, and I think "we thought we were going to die" although unjustified would be an understandable reaction.

Perhaps you should have been in the cabin on the flight, then you could have had a bellyful of laughs Bruce Wayne.

The failure was on a chem milled doubler, (Upper lobe, above and behind the 1L door). Aircraft is quarantined pending NTSB investigation. I have some pics but i can't post them??
